The compounds of Examples 1 to 46 may also be prepared as R- or S-enantiomers or as mixtures as regards the carbon atoms bearing the substitutents R1 (when this is other than H), R3 and R4, respectively. - The compounds of formula 1, in free form or in pharmaceutically acceptable salt form exhibit valuable pharmacological properties, e.g. inhibiting activity of LFA-1/ICAM-1, -ICAM-2 or -ICAM-3 interactions or inhibiting inflammation, e.g. as indicated in in vitro and in vivo tests and are therefore indicated for therapy.
- The assay measures the binding of soluble human ICAM-1 to immobilized human LFA-1. LFA-1 is purified from JY cells, a human lymphoblastoid B cell-line, by immunoaffinity chromatography as described by Dustin et a/. (J. Immunol. 148, 2654-2663, 1992). ICAM-1 mouse Cκ fusion protein (ICAM-1) is produced using the baculovirus system as described by Weitz-Schmidt et al. (Anal. Biochem.238,184-190, 1996).
- Purified LFA-1 is diluted 1:20 in phosphate buffered saline (PBS) containing 2 mM MgCl2, pH 7.4 and coated onto microtitre plates (Nunc) at 37°C for 3h. Plates are blocked with 1% heat-treated BSA in PBS for 2 hours at 37°C followed by a washing step using PBS, 2mM MgCl2, 1% fetal calf serum, pH 7.4 (assay buffer). Compounds dissolved at 10 mM in DMSO are diluted in assay buffer and added to the plates. Biotinylated recombinant ICAM-1 in assay buffer (6 µg/ml) is added and allowed to bind at 37°C for one hour. After incubation, wells are washed with assay buffer. Streptavidin-peroxidase diluted 1:5000 in assay buffer is added and incubated for 45 min at 37ºC. Plates are then washed with assay buffer and 2.2'-azino-bis(3-ethylbenzothiazoiine-6 sulfonic acid) diammonium salt substrate solution is added to each well. The reaction is stopped after 20 min and bound ICAM-1 is determined by measuring the optical density at 405 nm in a microplate reader.
- In this assay, compounds of formula I inhibit adhesion of LFA-1 to ICAM-1 with an IC50 ≤ 30 µM, preferably 0.05 to 30 µM. Compounds of Examples 1 and 3 have an IC50 of 0.44 and 0.07 µM, respectively, in this assay.
- Thioglycolate is injected i.p. to mice and immediately thereafter the compound to be tested is given s.c. The mice are killed after 4 hours, the peritoneal cavity lavaged and total number of neutrophils in the lavage fluid is determined.
In this assay, the compounds of formula I inhibit thioglycolate induced neutrophil migration when administered p.o. at a dose of from 0.001-50 mg/kg either at the time of thioglycolate injection or 3 hours before. - Groups of 8 female NMRI mice are sensitized on the shaved abdomen with 50 µl of oxazolone (Sigma, 2% in acetone) and challenged with 10 µl of 0.2 or 2.0% oxazolone on the inner surface of the right ear 7 days later. The low concentration of oxazolone for induction of the elicitation phase is used for testing compounds on systemic activity whereas the high concentration is applied for systemic testing. The unchallenged left ears serve as normal controls and dermatitis is evaluated from the individual differences in pinnal weight, which is taken as a measure of increase in inflammatory swelling 24 h after the challenge. Dermatitis is evaluated in test- and for comparison in control groups. The test groups are treated with the test compounds either orally (twice, 2 h and immediately before challenge), subcutaneously (immediately before challenge) or topically (30 min after challenge at the site of elicitation of the ACD); the controls are treated similarly with the vehicles alone. For oral and subcutaneous administration the compounds are administered in an oil in water emulsion, for topical administration the compounds are prepared in a mixture of ethanol, acetone and dimethylacetamide. The data of the test- and the vehicle-treated control groups are statistically analysed by ANOVA followed by Dunnet T-test (normal distribution or data) or by H and U-test, respectively. When administered p.o. at a dose of from 0.1 to 10 mg/kg, compounds of formula I inhibit the elicitation phase of allergic contact dermatitis. Compound of Example 3 has an inhibiting effect in this assay of 40% when administered p.o. at a dose of 2 x 3 mg/kg, or of 50% when applied topically at a dose of 10 mM.
- The compounds of formula I are, therefore, useful in the treatment and/or prevention of diseases or disorders mediated by LFA-1/ICAM-1, -ICAM-2 or -ICAM-3 interactions e.g. ischemia/reperfusion injury e.g. myocardial infarction, stroke, gut ischemia, renal failure or hemorrhage shock, acute or chronic rejection of organ or tissue allo- or xenografts, cancer, infection diseases such as septic shock, adult respiratory distress syndrome, or traumatic shock. The compounds of formula I are also useful in the treatment and/or prevention of acute or chronic inflammatory diseases or disorders or autoimmune diseases e.g. rheumatoid arthritis, osteoarthritis, systemic lupus erythematosus, hashimoto's thyroidis, multiple sclerosis, myasthenia gravis, diabetes type I and uveitis, asthma, inflammatory lung injury, inflammatory liver injury, inflammatory glomerular injury, cutaneous manifestations of immunologically-mediated disorders or illnesses, inflammatory and hyperproliferative skin diseases (such as psoriasis, atopic dermatitis, alopecia aerata, allergic contact dermatitis, irritant contact dermatitis and further eczematous dermatitises, seborrhoeic dermatitis, lichen planus, pemphigus, bullous pemphigoid, epidermolysis bullosa, urticaria, angioedemas, vasculitides, erythema multiforme, cutaneous eosinophilias, lupus erythematosus, acne, granuloma annulare, pyoderma gangrenosum, sun bums or toxic epidermal necrolysis), inflammatory bowel disease, Crohn's disease, ulcerative colitis, ophthalmic inflammatory diseases or immune-mediated conditions of the eye, such as autoimmune diseases, e.g. keratoplasty and chronic keratitis, allergic conditions, e.g. vernal conjunctivitis, inflammatory conditions and comeal transplants. For the above uses the required dosage will of course vary depending on the mode of administration, the particular condition to be treated and the effect desired. In general, satisfactory results are indicated to be obtained systemically at daily dosages of from about 0.1 to about 100 mg/kg body weight. An indicated daily dosage in the larger mammal, e.g. humans, is in the range from about 0.5 mg to about 500 mg, conveniently administered, for example, in divided doses up to four times a day or in retard form.
- For topical use satisfactory results are obtained with local administration of a 1-3 % concentration of active substance several times daily, e.g. 2 to 5 times daily.
- The compounds of formula 1 may be administered systemically or topically, by any conventional route, in particular enterally, e.g. orally, e.g. in the form of tablets or capsules, topically, e.g. in the form of lotions, gels, ointments or creams, or in a nasal or a suppository form. Percutaneous administration via patches or other delivery systems may also be a possible route for prevention or treatment of above diseases.
- Pharmaceutical compositions comprising a compound of formula I in free form or in pharmaceutically acceptable salt form in association with at least one pharmaceutical acceptable carrier or diluent may be manufactured in conventional manner by mixing with a pharmaceutically acceptable carrier or diluent. Unit dosage forms for oral administration contain, for example, from about 0.1 mg to about 125 mg of active substance.
- Topical administration is e.g. to the skin. A further form of topical administration is to the eye.
- The compounds of formula I may be administered in free form or in pharmaceutically acceptable salt form e.g. as indicated above. Such salts may be prepared in conventional manner and exhibit the same order of activity as the free compounds.
